Acquired
Benign Migratory Glossitis ("Geographic Tongue")
 
Loss of filiform papillae on certain areas of the tongue that appear smooth, red, and shiny. The areas “migrate” by progression of papillae loss at the leading edge and regeneration at the other end.
 
Usually noted on the dorsum of the tongue.
 
Etiology unknown, self-limiting.
 
Treatment: None known and unnecessary as it poses no problem. May be irritated by acidic foods.
 
Complete glossitis is associated with underlying systemic conditions, especially nutritional deficiencies of iron, folate, or B12. Refer to Chapter 12: Systemic Disease > Oral Manifestations for more information

Morsicatio Buccarum
 
Chronic, often subconscious, cheek biting that results in mucosal shredding, erythema, ulcers or
Leukoplakia: A condition commonly considered precancerous in which thickened white patches of epithelium occur on the mucous membranes especially of the mouth.
leukoplakia in the areas of biting. Usually symmetric along the buccal mucosa.
 
Biting may also involve the labial and lingual mucosal surfaces.
 
Diagnosis can be made on clinical findings.

Pyogenic Granuloma
 
Red, painless masses usually located on the gingiva. Characterized by bleeding with minor trauma.
 
Caused by vascular overgrowth in response to a local irritant or trauma.
 
May require surgical excision and may recur.
 
 
Geographic tongue is a non-pathologic variant of normal.
 
The buccal mucosa is the most common site of chronic biting.
 
Bleeding in response to minor trauma is characteristic of a pyogenic granuloma.
